The present invention provides a method for driving personal input device. The method is executed by a display. The display is connected with a personal input device. A first processing unit of the display drives the personal input device. The display receives a first event message from the personal input device. The first processing unit processes the event message to give a first event parameter, and updates the status of a cursor in a display picture according to the first event parameter. In addition, the first processing unit processes the first event message to generate a second event message, and transmits the second event message to an electronic device via a display data channel/command interface (DDC/CI).
Legal claims defining the scope of protection, as filed with the USPTO.
5. The method for driving personal input device of claim 1, wherein said first event message includes a device descriptor, a configuration descriptor, a string descriptor, an interface descriptor, and an endpoint descriptor to indicates said movement of said personal input device.
6. The method for driving personal input device of claim 1, wherein said first event parameter includes coordinate information of said cursor in said display picture to indicates said movement of said personal input device.
7. The method for driving personal input device of claim 1, wherein said personal input device is connected to said display device via a USB port, a parallel port, or a wireless communication transceiver.
8. The method for driving personal input device of claim 1, wherein said electronic device is a personal computer, a multimedia player, or a game console.
9. The method for driving personal input device of claim 1, wherein said second event message includes a button event, a cursor event, a scroll-wheel event, and a control event.
10. The method for driving personal input device of claim 4, wherein said on-screen display menu includes options of display settings for the display picture and a display region of the on-screen display menu in the display picture.
12. The display device of claim 11, wherein said first processing unit acquires a second event parameter according to said first event message and converts a second event parameter to said second event message according to a display data channel/command interface protocol.
13. The display device of claim 12, wherein said picture signal is generated by a second processing unit in said electronic device, said second processing unit recovers said second event parameter from said second event message and processes said second event parameter with software programs in execution to generate said picture signal.
14. The display device of claim 11, wherein said first processing unit determines if said first event parameter corresponds to an on-screen display menu, and said first processing unit generates graphical information of said on-screen display menu in said display picture corresponding to said first event parameter if said first event parameter corresponds to said on-screen display menu.
15. The display device of claim 11, wherein said first event message includes a device descriptor, a configuration descriptor, a string descriptor, an interface descriptor, and an endpoint descriptor to indicate said movement of said personal input device.
16. The display device of claim 11, wherein said first event parameter includes coordinate information of said cursor in said display picture to indicates said movement of said personal input device.
17. The display device of claim 11, wherein said input device connector is a USB port, a parallel port, or a wireless communication transceiver.
18. The display device of claim 11, wherein said electronic device is a personal computer, a multimedia player, or a game console.
19. The display device of claim 11, wherein said second event message includes a button event, a cursor event, a scroll-wheel event, and a control event.
20. The display device of claim 14, wherein said on-screen display menu includes options of display settings for the display picture and a display region of the on-screen display menu in the display picture.
